Aerial view of Mauna Loa's summit caldera, Moku‘āweoweo, captured by Civil Air Patrol on Sunday, October 20, 2019. Lua Poholo is the name of the pit crater in the bottom left corner of the image. Cones that formed during the 1940 and 1949 eruptions of Mauna Loa are visible in the background, as well fissures that extend through the center of the caldera. These fissures formed during the most recent eruption of Mauna Loa, in 1984.

Mauna Loa: Preparing for the next eruption of Earth’s largest active volcano

Storymaps, or geonarratives, are web maps that incorporate interactive maps with supportive text and photos. This geonarrative provides an overview of Mauna Loa’s eruptive history and hazards and includes interactive maps and datasets to help Island of Hawai‘i residents prepare for the next eruption.  Mauna Loa erupted most recently in 1984, and will erupt again in the future, posing significant risks to people living on the flanks of the volcano. The geonarrative text is adapted largely from the USGS Fact Sheet “Mauna Loa—History, Hazards, and Risk of Living With the World’s Largest Volcano” (Trusdell, 2012).
